Flashcards

Epidermis

The outermost layer of skin, made of stratified squamous epithelium, where new cells with keratin push old cells to the surface.

Keratinization

The process where new cells with keratin push old cells to the surface, taking about 40-56 days for new cells to reach the surface.

Stratum Basale (Germinativum)

The deepest layer of the epidermis, containing actively dividing cells that replace lost cells.

Stratum Spinosum

A layer of the epidermis with cells slightly separated by tissue fluid, joined by delicate extensions of cytoplasm, providing strength and flexibility to the skin.
